1. A multilayer ceramic electronic component, comprising:
a base component being substantially a rectangular prism;
a first external electrode;
a second external electrode; and
a protective layer,
the base component including a plurality of ceramic layers and a plurality of internal electrode layers with different polarities alternately stacked on one another, the base component including a first surface and a second surface opposite to each other in a stacking direction of the plurality of ceramic layers and the plurality of internal electrode layers, a first end face and a second end face opposite to each other, and a first side surface and a second side surface opposite to each other, the plurality of internal electrode layers being exposed on the first side surface and on the second side surface, the plurality of internal electrode layers including internal electrode layers with a first polarity exposed on one of the first end face or the second end face and internal electrode layers with a second polarity exposed on the other of the first end face or the second end face,
the first external electrode being connected to the internal electrode layers exposed on the first end face, the second external electrode being connected to the internal electrode layers exposed on the second end face,
each of the first external electrode and the second external electrode extending to at least one of the first surface or the second surface and including a first terminal side surface flush with the first side surface and a second terminal side surface flush with the second side surface,
the protective layer comprising a ceramic material, the protective layer covering the first side surface, the second side surface, and the first terminal side surface and the second terminal side surface of each of the first external electrode and the second external electrode.
